“…This paucity of vertebrate consumption is consistent with other studies that relied on macroscopic analyses of open-habitat chimpanzee faecal specimens (Suzuki, 1966;McGrew, 1983;Pruetz, 2006;Yoshikawa and Ogawa, 2015), but contrasts with recent observations at Issa. A 2015 report of blue duiker consumption at Issa (Ramirez-Amaya et al, 2015) and two additional observations since then (Piel and Stewart, unpublished data) support earlier discussions on the limitations of using indirect methods to reveal chimpanzee meat-eating (Boesch and Boesch, 1989).…”

Comparative data on the diets of extant primates inform hypotheses about hominin resource use. Historically, data describing chimpanzee diets stem primarily from forest-dwelling communities, and we lack comparative data from chimpanzees that live in mosaic habitats that more closely resemble those reconstructed for Plio-Pleistocene hominins. We present data on the diet of a partially-habituated community of open habitat chimpanzees (Pan troglodytes schweinfurthii) from the Issa valley, western Tanzania, collected over a four-year period. Based mostly on macroscopic faecal analysis, Issa chimpanzees consumed a minimum of 69 plant species. There was no relationship between plant consumption and either fruit availability or feeding tree density; the most frequently consumed plant species were found in riverine forests, with woodland species consumed more frequently during the late dry season. We conclude by contextualising these findings with those of other open-habitat chimpanzee sites, and also by discussing how our results contribute towards reconstructions of early hominin exploitation of mosaic landscapes.

“…Entamoeba histolytica has been found in colobus monkeys (Gillespie et al ., 2005) and in non-primate mammals, such as dogs (Alam et al ., 2015); therefore, transmission could occur through consumption of cysts from infected animals. Reports show that the Issa Valley chimpanzees consume blue duiker ( Philantomba monticola ) meat, but not red colobus monkeys or bushpigs, even though they are both present in the habitat (Ramirez-Amaya et al ., 2015). This further supports the possibility that the Gombe chimpanzees become infected by ingesting cysts from the colonic content of their prey.…”

Entamoeba histolytica is an enteric parasite that infects approximately 50 million people worldwide. Although E. histolytica is a zoonotic parasite that has the potential to infect nonhuman primates, such transmission is poorly understood. Consequently, this study examined whether E. histolytica is present among humans, chimpanzees and baboons living in the Greater Gombe Ecosystem (GGE), Tanzania. The primary aims were to determine patterns of E. histolytica infection in a system with human-nonhuman primate overlap and to test associations between infection status and potential risk factors of disease. Entamoeba spp. occurred in 60.3% of human, 65.6% of chimpanzee and 88.6% of baboon samples. Entamoeba histolytica occurred in 12.1% of human, 34.1% of chimpanzee and 10.9% of baboon samples. Human E. histolytica infection was associated with gastrointestinal symptoms. This was the first study to confirm the presence of E. histolytica in the GGE. The high sample prevalence of E. histolytica in three sympatric primates suggests that zoonotic transmission is possible and stresses the need for further phylogenetic studies. Interventions targeting better sanitation and hygiene practices for humans living in the GGE can help prevent E. histolytica infection in humans, while also protecting the endangered chimpanzees and other primates in this region.

“…Wild chimpanzees regularly catch and eat mammals and, more rarely, birds throughout sites in Africa (e.g., Goodall 1986;Boesch & Boesch 1989;Kuroda et al 1996;Hosaka et al 2001;Newton-Fisher et al 2002;Watts & Mitani 2002;Pruetz & Bertolani 2007;Fujimoto & Shimada 2008;Nakamura & Itoh 2008;Ramirez-Amaya et al 2015). While there are reports of chimpanzees capturing and interacting physically with other animals without eating them, often involving adolescent or immature chimpanzees, such interactions appear to be rare in the wild (e.g., Hirata et al 2001;Carvalho et al 2010;Hockings et al 2012).…”

Abstract: * The genus is present at Issa, but it is uncertain whether the species is similar across Tanzanian sites. ** Other genera of the same Family exist at Issa.
